Therefore, the scientists were able to conclude that these neurons in the body determine the regulation of sleep and wakefulness.

Further, experts who study the subject, continued their work, are already conducting research on humans. 1000 participants of the experiment for 7-10 days every two years, worn on the wrist specially designed device that records everything the motion produced by man. During the tests, it was noted a decrease in the number of neurons in the ventrolateral preoptic area in people who are sick Alzheimer And in older participants in the experiment. These volunteers in average daily sleep an hour less than the young people.

According to the initiators of such a study, the results will help them to develop a fundamentally new medicines to help overcome insomnia. They will are based on possibilities regulate the function of of specific of neurons. This drug is harmless, in contrast to those preparations in which now overcome insomnia.
